Answer 1

Answer:

First 51 multiples of 6 are-

(6,12,18,24,30,36,42,48,54,60,66,72,78,84,90,96,102,108,114,120,126,132,136,144,150,156,162,168,174,180,186,192,198,204,210,216,222,228,234,240,246,252,258,264,270,276,282,288,294,300,306)/51=52k

=7140*51=52k

=364140=52k

k=394140/52

Answer 2

Answer:

k=3

Step-by-step explanation:

6, 12, 18, ⋯ 306

S = n/2(a+l)

= 51/2(6+306)

= 51/2(312)

= 51(156)

Average of multiple of 6= 52k

51(156)/51 = 52k

156 = 52k

k= 156/52

k=3
